[0047] S1: Based on the future power generation plan of the generator set, the corresponding coal formula group is determined in the preset coal formula corresponding table, and the coal filling of the double partitions of the raw coal bin is configured based on the coal formula group.

[0048] It should be understood that the preset coal formula correspondence table refers to a coal ratio plan prepared in advance according to different load conditions and coal quality requirements during the power generation process.

[0049] S2: Based on the coal burning requirements of the boiler at different time nodes, a raw coal supply rate strategy is constructed for different partitions of the raw coal bunker.

The coal supply rate strategy includes the arrangement of coal supply rates in different zones. For example, at different time nodes, the coal supply rates in different zones are different.

[0051] For example, there are partitions A and B, the coal supply rate of partition A at time node 01 is set to 1v, and the coal supply rate at time node 02 is set to 2v. The overall coal supply rate setting strategy of partitions AB is called the original coal supply rate strategy.
